# CPRM Annotation App

This Space hosts the first-round CPRM annotation interface for 6 calibration bundles.

## Required Space Secrets

- `HF_TOKEN`: write token with access to the target dataset repo
- `HF_DATASET_REPO`: target dataset repo, for example `Zhuohan/cprm-annotations`
- `HF_DATASET_SUBDIR` (optional): defaults to `annotations`
- `ANNOTATION_APP_PASSWORD` (optional): shared app password for annotators

## Storage

This app supports two save modes:

- local JSON fallback
- Hugging Face dataset-backed persistence when `HF_TOKEN` and `HF_DATASET_REPO` are set

For the free Spaces workflow, use a dataset repo as the persistent annotation store.
